error: cached cgu 0x4a9cmec5w3kmvnwylp7mwkt should have an object file, but doesn't
Note that the "cgu" identifier stays consistent across compilations ( 0x4a9cmec5w3kmvnwylp7mwkt
).
Running cargo clean
and then re-compiling solved the issue. Note that I am using RustRover as my IDE, though compiling directly with cargo build
made no difference. I'll leave a new comment on this issue if I can recreate it.
